Like many online services, Google gathers data on its users, and this makes some people squeamish. If you'd like to minimize the amount of data Google collects from you (and uses on you) here are some steps you can take.

Steps

Opt out of having ads tailored to your demographic. Go to the Ad Preferences page and click on "Opt Out" then click on the blue "Opt Out" button you are presented with.

3

Sign out of Google and go back to the web history page. Choose "Disable customizations based on search activity."

4

Stay signed out of Google as much as possible. This will give Google less search data to collect. Since signed-out users still see ads based on their search terms,[1] however, this step does not guarantee 100% anonymity. To make sure you stay signed out, disable automatic log-in here.

Go Incognito if you are using Google Chrome. Note: You can also select Private Browsing using Firefox. Select "Tools" then click on Private Browsing found in the drop down bar.
